Session variable getting lost

[radalin]

Hi,
I'm using session variables for my member system. I got a session id which is kept as a session variable then have a session table etc. I get user info throught this session id. But the thing is in my local, session variables not saved! They are lost and every time I refresh the page they are recreated. There is a check, if there is no session then create a one, else use the existing one. I should be missing something in the php.ini or something I'm not sure about it.

Any idea why can this happen? I have wamp 1.6.4 installed on my computer with Mysql 5 and PHP 5 options.

Thank you for your time

Can you post your code?

[code]
session_start();
echo $_SESSION['SID'] ; //echo no1
if ( ! $_SESSION['SID'] )
{
$_SESSION['SID'] = md5( uniqid(rand(),1) );

setSession( $_SESSION['SID'] ) ;
}
echo $_SESSION['SID'] ; //echo no2
[/code]

and the setsession function is

[code]
function setSession($sid = "")
{
if ($sid == "")
{
$_SESSION['SID'] = md5( uniqid(rand(),1) ) ;
$sid = $_SESSION['SID'] ;
}

$this->db->connect() ;

if (MDB2::isError($this->db))
die($this->db->getMessage());

$query = "SELECT session_id FROM sessions WHERE session_id = '" . $sid ."' ";

$result = $this->db->queryOne($query);

if (MDB2::isError($result))
die($result->getMessage());


//If this sid is previously set before then we have already have a value
//for that user...
if ( $result == $sid )
return 0 ;

//And if such sid does not exists
$query = "INSERT INTO sessions (session_id,session_start,session_last_activity_date,session_ip,session_logged_in,user_id) VALUES ('$sid','" . date('m-d-Y H:i:s') ."','" . date('m-d-Y H:i:s') ."','". $_SERVER['REMOTE_ADDR'] ."','-1','-1')";

$this->db->_doQuery($query);

if ( MDB2::isError($this->db) )
die($this->db->getMessage());

$this->db->disconnect() ;

return 1 ;
}
[/code]

The problem is at echos. While first one does not print anything the second one does. (I assume you already entered to the site and clicked a few links.). setSession() function is called and then a new session id created. As the session id changes all the time, I can't reach to the right session row. I wonder why the session variables are lost.

I checkes on somewhere else and I saw that my code worked perfectly. So it should be somethin about the php settings. Which setting should I check?
